where is the particle when t = 5?

Example 2

A cat climbing up and down a tree ends at height 3 feet after 10 seconds. If  feet, how high in the tree was the cat at time t = 0?

Example 3

Let s(b) = 10.

(a) If , that means we had to take 3 away from s(a) in order to get to s(b).

(b) If , that means we had to add 7 to s(a) in order to get to s(b).

Example 4

A bicyclist is 10 miles from home after 3 hours of riding and 30 miles from home after 5 hours of riding. If her velocity is given by the function v(t), what is ?

Example 5

If s(0) = 3 and , what is s(6)?
